A prevalence of posttransplantation cancers compared with cancers in people with human immunodeficiency virus/acquired immunodeficiency syndrome after highly active antiretroviral therapy.
BACKGROUND
Organ transplant recipients and human immunodeficiency virus & acquired Immunodeficiency Syndrome (HIV/AIDS) patients have immune deficiencies that are possible mechanisms to develop malignancy. The type of cancers associated with these 2 conditions might elucidate this premise.


OBJECTIVE
Our aim was to compare prevalence and type of cancers between kidney transplant recipients and patients with HIV/AIDS.


METHODS
We retrospectively reviewed 344 patients who underwent kidney transplantation from 1973 to 2007 compared them with 863 subjects with HIV/AIDS at the HIV-Netherlands/Australia/Thailand Research Collaboration (HIV-NAT) from 1997 to 2007. AIDS-defining cancers were excluded from the analysis. We compared the relative tumor risk with the age- and gender- matched general population of metropolitan Bangkok.


RESULTS
The overall cancer risk for kidney transplant recipients (standardized incidence ratio [SIR] = 4.21) was comparable with HIV-infected patients (SIR = 3.88). Uroepithelial cancer was the most prevalent type in kidney transplant recipients, whereas cervical cancer was the most common malignancy in HIV-infected patients. The risks of developing hepatoma and non-Hodgkin's lymphoma were comparable between the groups.


CONCLUSIONS
Kidney transplant recipients and HIV-infected patients show increased overall risks of certain types of cancers.
